It’s official: Denmark has voted No with Comments to ISO/IEC DIS 29500 OOXML. See Danish Standards’ press release (in Danish). They are submitting 64 pages of comments, and state that Denmark will work for an approval assuming the comments will be addressed.
I’ve read through the comments, and find them balanced and thorough. It will require some substantial changes to EOOXML for it to address these comments. However, addressing the comments will also require changes to OpenDocument, because the gist of the comments is to ensure interoperability between the ISO document standards.
Good thing so many companies have recently joined the various standards committees, because if ISO follows the Danish recommendations, lots of work is yet to be done.
